Clear night, full moon, a huge dark object above my home.

I remember on night coming home from the store.  It was a full moon that night.
Sitting in the car with a friend, listening to his new stereo.  I was enjoying the evening and the light of the full moon, and the shadows it left.
Then, as I was looking around I noticed the shadows, were gone yet in the short distance there was still light, and shadows.
It was a clear night before and I had seen no clouds, so as I went to look up in the night sky, to see if there was a cloud, covering my moon.
I was stunned, shocked, in full AW, could not believe what I was seeing.  Above my home was this round object above our house, at a Maple trees height.
We, lived in an old school house, (chiminey was 7ft. tall)  and with the trees right there it was kinda easy to judge height.
There was absolutly no sound coming from it.  I got out of the car, and went up to the house and opened the door, and hollared at my mom to come here, she didn't come said she was busy.  As, I stood there holding the, door I again hollared at my mom to come here.  She told me again she was busy.  Thats when I hollared again, mom get your damn ass out here, you have to see this, my dad was mad in the background.  She, came and was she pissed, As, I pointed up, I apologized to her.  we both stood there looking, shaking, nervous , excited and all.  In disbeleif.
As, we stood there watching, we seen lights come on, they were around the outside rim, of th craft.  Still, no sound.  Then, it moved away very slowly, and still no noise.  It headed into the field to the west. And, just that fast it was gone, in a flash.
Witness indicates that the date of the sighting is approximate.  PD
